Yes, I read the warning and it eventually came back to me as a possibility - it just took too long for me to question that a brand new, off the shelf part would be the problem. FAR more often it is some errant wire or lack of understanding... in my case anyway.
If I've learned anything it is that those weird intermittent problems that come and go are most often related to power supply. Wires don't move and semiconductors don't magically heal - only to fail again - in a random pattern. Well, here's to posterity and "Good Luck" to the next guy.
Cheers,
